My friend Ilona had her toilet door replaced by a big strong guy, who can lift up and push around the heaviest things as if they just were lego pieces.
When the doorhandles were placed, he tried them from outside and inside to check if they would work. Then he had the good idea to get inside the toilet room and lock the door to try out if it also worked once the door closed. Indeed it did, it worked so well that he couldn't get out anymore and of course he had left all his tools outside. Now Ilona's toilet is a just like a box room and a big man has not much room in it, the only thing he could do to gain some space was sitting down on the throne. My friend tried from outside to slip a screwdriver under the door, but unfortunately the man had done such a good work and the door fitted so perfectly that there was not even room for a piece of paper.
The poor guy started to panic inside the toilet and wanted to get out. Outside my friend got more and more nervous listening to the moaning and complaints of the guy inside. Finally she was so unnerved that her hands trembled so much that she couldn't handle the screwdriver. She tried and tried and it didn't work.
Suddenly inside the toilet there was no sound anymore so that she thought he had fainted or even worse. The only solution was, to make a big hole into the brandnew door, to eventually get a corpse out. She took a hammer and banged as strong as she could on the screwdriver which she had stuck in the keyhole.
Suddenly there was a "click", the door went open and into her arms fell a completely exhausted 100 kg (220 lbs) man, white like a bedsheet and dizzy so that she had to carry him to her sofa. I don't know how she handled that, because my friend is a rather petite person with a weight of 50 kgs ( 110 lbs) and it was a miracle that the big guy didn't make a pancake out of her, when he fell into her arms after his liberation. They both of course had a shock, and it took several beers before big guy recovered from his shock and could go home, this time a little dizzy from the good Belgian beer and in an excellent mood. Fortunately he could walk home ... alive.
My friend took the key out and put it away, she had no desire to live this again.
